COLTER-FASTENER.

Specification of Letters Patent.

Patented J an. 8, 1918.

Application filed October 15, 1917. Serial No. 196,713.

To all whom it may concern:

Be it known that I, PATRICKVV. MCFALL, a citizen of the United States, residing at Madison, in the county of St.'Francis and State of Arkansas, have invented a new and useful colter-Fastener, of which the follow ing is a specification.

This invention relates to colter fasteners and is designedmore particularly as an improvement upon the structure disclosed in Patent N o. 79l,73l issued to me on July 18, 1905. V

In my patented structure it is necessary that the colter be extended through the beam and the same can thus be used solely in con nection with plows requiring a colter to be supported at the center of the point.

One of the objects of the present invention is to provide a fastener which will hold a colter either within the beam so as to extend to the center of the point of the plow, or along side of the beam for use in connection with moldboard or turning plows, it being possible to change the colter from one position to the other quickly and to hold it securely in either position.

With the foregoing and other objects in view, which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the pre ferred form of the invention has been shown.

In said drawing":

Figure 1 is a side elevation of a portion of a beam having the present improvements combined therewith. the colter being shown held to one side of the beam.

Fig. 2 is a plan view of the structure shown in Fig. 1, the colter being shown in section.

Fig. 3 is a plan view on a reduced scale of the bottom plate of the fastener.

Referring to the figures by characters of reference 1 designates a portion of the beam of a plow, there being an inclined opening 2 extending therethrough. Secured upon the beam is a plate 3 preferably formed with transverse ribs 4. projecting into transverse grooves 5 in the beam. This plate has an upstanding web 6 arranged between enlargements 7 which are adapted to receive fastening bolts 8 and arranged at each side of the web 6 is an elongated recess the end walls of which are inclined so that when the plate is in position on the beam 1, the end walls of one of the recesses will aline with the end walls of the opening 2 in the beam. Likewise, when the plate is in position, the inner wall of the other side recess therein will lie flush with the side of the beam 1, as shown in Fig. 2. A slot 9 is formed in the plate 3 and alines with the slot 2 in the beam.

Fastening bolts 10 are extended through the ends of the plate 3 and downwardly through the beam 1, these bolts also extending through apertures 11 formed in a bottom plate 12 which has a laterally extending flange 13 projecting beyond the side of the beam 1. A slot ll is formed in this plate 12 and alines with the slot 2 in the beam 1 and another similar slot 15 is formed in the flange 3 with its inner side flush with the side of the beam 1.

A portion of a colter has been shown at 16. iVhen it is desired to secure this colter in position for use in connection with a moldboard or turning plow, the same is inserted through the slot 15 so as to rest against one side of the beam 1, the upper portion of the colter being held against the outer side of the web 6 by a clamping plate 17 which is fastened to the enlargements 7 by the fastening bolts 8. However, should it be desired to use the colter so as to extend to the point of a plow, said colter can be extended upwardly through the slot 14, opening 2 and the slot 9 so as to rest against the inner side of the web 6 where it will be clamped by means of the fastening plate 17 which can be removed and placed upon the side of the enlargement 7 and held by the bolts 8. This last arrangement has been shown in my patent hereinbefore mentioned.

It has been found that by providing a fastener such as described, a colter can be quickly and readily shifted to either of two positions thus to adapt it for use in connection with any kind of plow.

\Vhat is claimed is 1. The combination with a plow beam, of a bottom plate secured thereto and having a laterally extending flange provided with a colter receiving slot, the inner side of the slot being flush with the side of the beam, a

plate secured upon the beam and having an upstanding web one side of which is flush with the side of the beam, there being end enlargements on the plate and projecting laterally beyond the web, said enlargements and web cooperatin g to term a colter receiving recess, a clamping plate for engaging the colter receiving slotextending downwardly therethrough, of a bottom plate secured to the beam and having a laterally extending flange, there being a colter receiving slot within the plate registering with the slot in the beam and another'colter receiving slot in the flange with its inner side wall flush with one side of the beam, a top plate secured upon the beam and having a slot registering Copies of this patent may be obtained for with the slot in the beam, there being an upstanding web upon the top plate and enlargements at the ends of the web, saidenlargements and web cooperating to form colter receiving recesses at each side of the web, one side of said web being flush with one wall of the slot in the top plate and the other side of said web being flush with one side of the'beam, and a clamping plate detachably secured to the enlargements and at either side of the web to hold a colte'r in either of said recesses.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

PATRICK V. M FALL.
